    Superheated water - Wikipedia

    Superheated water is liquid water under pressure at temperatures between the usual boiling Specific heat capacity at constant pressure also increases with temperature, from 4.187 kJ/kg. In the above example, only 30% of the water would be converted to vapour on decompression from 5 MPa to atmospheric pressure.
